Furuno radar 1621 do not show targets

Furuno radar 1621 starts, antena rotating but NO targets displayed. Shows only random dots - something like a "noise". Radar was transmiting for 58 hrs total. The problem occured suddenly - from good performance to no performance. How can I detect the faulty part?

You may have a faulty magnetron or one that has gotten old. They do have a life. Find out how many hours you have on the unit and give furuno a call. They will more than likely tell you what they think the problem is.

If you have no radar targets, go to longest range 24 miles, gain full, rain and sea minimum, do you have noise, if so, need magnetron, if not, need cable from display to dome.

Furuno 1621 radar will not power up


With a voltmeter, verify that you are getting 12V at the plug end of the power cable. If so, check the fuses (there should be one or two fuse holders on the back). If all of that fails you will need to send it in to Furuno for repair.

My model 1621 radar will not power up


I had exact the same problem with my furuno 1621, Furuno in Netherlands also say needs new mother board (650 euro!)

Problem is fixed

Problem is not the switch, but an Elco on the mother board. it's the small elco on the Mother board Cost just a few cents!

I hope You can fix Your radar too.
